Abstract EN

The importance of the research shows that the researcher has prepared three similar approaches in all its components and the content of their exercises and facilities of environmental repetitions and breaks except the formation of the summit is different in order to indicate the impact of each of the three formations on the research variables under study.

The research objectives were: -1- Preparation of different approaches to load configurations and their impact on the variables under study and achievement of distance runners 400 m hurdles2-Identify the differences between the tests and pretest posttest in the variables under study and achievement of the experimental groups3- Identify the differences in tests and telemetry in the variables under study and achievement between the two experimental groupsIt was concluded that: 1-Mechanisms for controlling systolic and diastolic blood pressure in the rest of the two groups were highly efficient to maintain the pressure values at their normal rates before and after the experimental method with little effect on the post-results.2-Both the rate of estimation of potassium sodium within the normal limits before and after the experimental method and this shows the efficiency of the body's internal functions by controlling the level of salts at its normal rates.

The most important recommendations were: 1-Use the method of crispy formation to develop physical characteristics under study and enzyme lactate and function indicators.2-The research sample is characterized by high in each of the functional indicators (breathing and heart rate)
